The MC who was transmigrated was at the start labelled as a wisp or fragment of the god of knowledge and was transmigrated into this otome game world because of a bet made with the goddess Gaia. She transmigrates into this world as the familiar of the young villainess who was crying alone after she was poisoned (The MC can see game statuses) and becomes her familiar, in the form of a oni, and promises to be her familiar. Fast forward to the next day and the villainess is getting bullied by some kid or something and he starts using some rare manipulation power on her. The MC being a fragment of the god of knowledge analyses his power and negates it, then proceeding to pin the kid down and humiliating him. This is all I remember and I would like to read it again so if anyone could help me out with this then that would be fantastic. Oh yeah, its also mentioned during the conversation with Gaia that the MC was the one who killed the god of knowledge and was the only remaining being that has any connections with him. Don't know if this helps just remembered it now. Oh yeah Im pretty sure its a Yuri novel as well.
